What is the difference between OnLoad method and Load event? I am developing WinForm controls. Should I register to Load event or override the OnLoad method? What are the advantages and the disadvantages of each one?

推荐答案

我会优先考虑 OnLoad ，因此您可以节省CPU周期来调用事件处理程序.

I'd go for overriding OnLoad, so you spare the CPU cycles to invoke the event handler.

如果从控件继承，则一般模式是重写方法；否则，请订阅该活动.

The general pattern is to override a method, if you inherit from a control; otherwise, subscribe to the event.

但记得调用基类的 OnLoad 方法，因为那是调用 Load 事件的地方.

But remember to call the base class' OnLoad method, because that's where the Load event invoked.
